    connections: only update .instance_serial when an instance
    
    Add .next_instance_serial and use that to track serial numbers.
    An established security label instantiates the connection twice:
       template -> parent -> child
    but only the child has a non-zero .instance_serial.
    
    (instantiated security label connection names could do with
    a re-think, perhaps incorporate the label, or perhaps
    include multi-level serial numbers)
